In the European Parliament seats are distributed according to a principle of degressive proportionality that privileges smaller member states. While serving the principle of state equality, this arrangement seems to violate the principle of citizen equality. In this article, I consider whether a deviation from the equal representation of citizens can be justified in the context of a supranational political community. The main thesis is that the conflict between citizen and state equality can be dissolved if we understand the European Union as based on a pouvoir constituant mixte. Today, each European finds herself in a dual role as an EU citizen and a state citizen. While the member state peoples strive for supranational democracy, they have an interest in preserving their domestic structures of self-government. Thus, the rules of representation in the EP can be reconstructed as an expression of the legitimate will of a dual constituent subject. *This is a revised version of an article published in Der Staat, 2/2014, translated by Ciaran Cronin.
